I've just now made a new index for Medical Care, Insurance, and Socialized Medicine. I don't know why I've not had this long ago.
The first (new) entry is Paul Krugman's "Health Care Confidential" artical from the New York Times, as quoted by Brad DeLong. It pretty much thrashes the libertarian-preferred idea that markets do it best. And it does it with the bane of ideology: real world facts.
If anybody would like to suggest the best sites that oppose the market-oriented provision of health care, I'd like to add some.
